The invention discloses a locking device of a semitrailer transportation container safety device, and relates to the technical field of semitrailer safety protection. The device comprises a rear protection plate and two rack plates, two L-shaped grooves are formed in each of the two ends of the rear protection plate, a U-shaped groove is formed in the middle of the rear protection plate, hollow seats are arranged on one sides of the two rack plates, movable rods are movably arranged in the two hollow seats, and locking mechanisms are arranged between the two movable rods and the rear protection plate. A supporting assembly is further arranged between the two movable rods and the rear protection plate. According to the device, through the locking mechanism and the supporting assembly, a U-shaped supporting plate in the supporting assembly is attached to the inner wall of a U-shaped groove, and the U-shaped supporting plate supports the rear protection plate, so that four L-shaped locking plates in the locking mechanism are attached to the inner walls of four L-shaped grooves, and the four L-shaped locking plates lock the rear protection plate; therefore, locking of the installed rear protection plate and supporting after locking are conveniently achieved, and the stability of the rear protection plate is effectively improved.

    本发明公开一种半挂车运输集装箱安全装置的锁紧装置,涉及半挂车安全防护技术领域;而本发明包括后防护板及两个机架板,后防护板的两端均开设有两个L型凹槽,后防护板的中部开设有U型凹槽,两个机架板的一侧均设有空心座,两个空心座的内部均活动设有活动杆,两个活动杆和后防护板之间设有锁紧机构,两个活动杆和后防护板之间还设有支撑组件;本发明中,通过锁紧机构及支撑组件,支撑组件中的U型托板与U型凹槽的内壁贴合,U型托板对后防护板进行支撑,使锁紧机构中的四个L型锁紧板与四个L型凹槽的内壁贴合,四个L型锁紧板将后防护板锁紧,从而方便的实现了安装后的后防护板的锁紧及锁紧后的支撑,进而有效的提高了后防护板的稳定性。
